#3 The Sarri-ball

No manager in the top tier of European football insists on playing a particular brand of football as much as Sarri and his inability to adapt resulted in Chelsea getting destroyed at the hands of Manchester City.
When you are playing against a team managed by a genius like Guardiola, not having a plan B is utter suicide and Sarri paid a hefty price for his lack of planning. Sarri’s system relies a lot on Jorginho and once Manchester City pocketed him, Chelsea went out of options and they struggled to move the ball forward to Eden Hazard and Gonzalo Higuain.
Chelsea made a tactical blunder by picking Marcos Alonso who lacks the pace and creativity to provide overlapping runs on the left flank. His usage of N'Golo Kante has raised a few eyebrows and he could have played him in a defensive midfield role in the second half to minimise the damage. Unless he changes his strategy, he will be making way for a new manager this summer.
